  1. What Did You do in the Shop Today?

    Thanks everyone! This is several hundred miles from seawater, but still in the east coast rainy zone. So paint finish required, but not hot dipping. Sandblasted, then zinc solids primer, then automotive primer, then 2 part epoxy top coat.

    Coffee table parts. And railing install day. Not a bad view.
  3. Le Pig

    It's the exit for the hardy hole in the face. Common for this style of anvil. Logical if you think about it, it's a pretty easy (short) punch and drift in a big block of steel, and as long as you go into it knowing that your shanks will be curved or angled no problem! The location also puts tooling to the off side for right handers like with German style anvils, so no worry about barking the nuckles on your hammer hand on a hardy.
  4. Need some info.

    Welcome aboard!
  5. Fly Press Sizes?

    It depends on the manufacturer. My Perkins #4 is bigger than what that anvilfire chart or the modern manufacturers call a #6.
  6. What Did You do in the Shop Today?

    Amen. Good advise there. Hope things work out friend Gergely.
  7. Champion no.1information

    Yes it's a dovetail. And having the lower dt blow out is probably the most comon problem with Champions, it's the #1 design flaw with them. I've seen what I think are original dies with an extended cross shaped lower section to provide more bearing in the dt. Here are some pics of my dies and keys. I ground, filed, and scraped new oversize female dovetails into the anvil (no sow block, grrr) and eventually used a hot fit larger key and the copper shim trick with a reverse taper smaller key to get it to stay put. Also included some awkward angle pics of the idler arm. This hammer is stuffed tight into a corner of the shop and for space reasons I mounted the motor down low and refersed the usual orientation of the arm. Also turned an extension for the pulley axle to get motor, idler, and main pulley to align with an oddball motor location. Thus the tight pictures but I hope you get the idea.

    Ha! Told you so! (Grin)
  9. Can You Please Evaluate My Tong Design

    Rings and clips on the bitter end of reins also create maximum clamping force, and allow the spring in the reins to absorb hammering impact without working loose. They also don't get in the way of rotating the tongs and work on the face of the anvil. Offset tongs allow the same function as your pass thru design while having a more simple and robust design. Only one rivet in the boss. You might be on to something with the hardy hole tong holder thou! Good idea.
  10. Build a tumbler. After tumbling to knock off scale or burnishing, you can apply oil based finishes with a tumbler by tossing in an oil soaked rag (beware the fire hazard thou).
  11. Holdfast

    Hold downs work using a combination of length, hight, very modest spring load, and wedge angle (some mystical ratio of hole diameter, shaft diameter, and hole depth.) If you have an oddly shaped hole you will need to play around with the variables to find what works for you.
  12. Holdfast

    Historically they were made from wrought iron and worked well for 1000 years or so. Zero hardness on the blacksmith's scale. Mild steel (a-36) works just fine as long as you keep your proportions within reason.
  13. No spring or mounting bracket

    Nice fix!
  14. It followed me home

    Lennox 14/18 tpi. Worth the money!
  15. What are the requirements of a forging press

    The reasons not to use a HF press for forging are many. Lack of speed, lack of stiffness, lack of replaceable parts, no limit switches, no safety shrouds on hydraulic parts (google hydraulic press flamethrower). So many wide open questions in the original question. Buy this book. Hydraulic Forging Press for the Blacksmith It's cheaper than a crappy press from HF and WAY cheaper than the mistakes, down time, injury, or worse from using the wrong tool.
